2.2 General safety and application notes for Lenze motors
(according to Low-Voltage Directive 2006/95/EG)
General
Lowvoltage machines have hazardous live and rotating parts and
possibly also hot surfaces.
Synchronous machines induce voltages at open terminals during
operation.
All operations concerning
commissioning and maintenance must be carried out by
qualified, skilled personnel (EN 501101 (VDE 0105100) and IEC
60364 must be observed). Inappropriate use creates the risk of
severe injury to persons and damage to material assets.
Lowvoltage machines may only be operated under the
conditions that are indicated in the section "Application as
directed".
The conditions at the place of installation must comply with the
data given on the nameplate and in the documentation.
Application as directed
Lowvoltage machines are intended for commercial installations.
They comply with the harmonised standards of the series
EN 60034 (VDE 0530). Their use in potentially explosive
atmospheres is prohibited unless they are expressly intended for
such use (follow additional instructions).
Lowvoltage machines are components for installation into
machines as defined in the Machinery Directive 2006/42/EC.
Commissioning is prohibited until the conformity of the end
product with this directive has been established (follow i. a. EN
602041).
Lowvoltage machines with IP23 protection or less are only
intended for outdoor use when applying special protective
features.
The integrated brakes must not be used as safety brakes. It
cannot be ruled out that factors which cannot be influenced,
such as oil ingress due to a defective Aside shaft seal, cause a
brake torque reduction.
Transport, storage
Damages must be reported immediately upon receipt to the
forwarder; if required, commissioning must be excluded.
Tighten screwedin ring bolts before transport. They are designed
for the weight of the lowvoltage machines, do not apply extra
loads. If necessary, use suitable and adequately dimensioned
means of transport (e. g. rope guides).
Remove transport locking devices before commissioning. Reuse
them for further transport. When storing lowvoltage machines,
ensure a dry, dustfree and lowvibration (veff ≤ 0.2 mm/s)
environment (bearing damage while being stored).
Installation
Ensure an even surface, solid foot/flange mounting and exact
alignment if a direct clutch is connected. Avoid resonances with
the rotational frequency and double mains frequency which may
be caused by the assembly. Turn rotor by hand, listen for unusual
slipping noises. Check the direction of rotation when the clutch
is not active (observe section "Electrical connection").
Use appropriate means to mount or remove belt pulleys and
clutches (heating) and cover them with a touch guard. Avoid
impermissible belt tensions.
The machines are half-key balanced. The clutch must be half-key
balanced, too. This visible jutting out part of the key must be
removed.
If required, provide pipe connections.
Designs with shaft end at bottom must be protected with a cover
which prevents the ingress of foreign particles into the fan. Free
circulation of the cooling air must be ensured. The exhaust air -
als the exhaust air of other machines next to the drive system -
must not be taken in immediately.

Electrical connection
All operations must only be carried out by qualified and skilled
personnel on the low-voltage machine at standstill and
deenergised and provided with a safe guard to prevent an
unintentional restart.This also applies to auxiliary circuits (e. g.
brake, encoder, blower).
Check safe isolation from supply!
transport, connections,
If the tolerances specified in EN 60034-1; IEC 34 (VDE 0530-1) -
voltage ±5 %, frequency ±2 %, waveform, symmetry - are
exceeded, more heat will be generated and the electromagnetic
compatibility will be affected.
Observe the data on the nameplate, operating notes, and the
connection diagram in the terminal box.
The connection must ensure a continuous and safe electrical
supply (no loose wire ends); use appropriate cable terminals. The
connection to the PE conductor must be safe. The plug-in
connectors must be bolt tightly (to stop).
The clearances between blank, live parts and to earth must not
fall below 8 mm at V
V
The terminal box must be free of foreign particles, dirt and
moisture. All unused cable entries and the box itself must be
sealed against dust and water.
Commissioning and operation
Before commissioning after longer storage periods, measure
insulation resistance. In case of values ≤ 1 kΩ per volt of rated
voltage, dry winding.
For trial run without output elements, lock the featherkey. Do
not deactivate the protective devices, not even in a trial run.
Check the correct operation of the brake before commissioning
low-voltage machines with brakes.
Integrated thermal detectors do not provide full protection for
the machine. If necessary, limit the maximum current.
Parameterise the controller so that the motor will be switched
off with I > I
risk of blocking.
Vibrational severities v
(P
If deviations from normal operation occur, e.g. increased
temperatures, noises, vibrations, find the cause and, if required,
contact the manufacturer. In case of doubt, switch off the low-
voltage machine.
If the machine is exposed to dirt, clean the air paths regularly.
Shaft sealing rings and roller bearings have a limited service life.
Regrease bearings with relubricating devices while the low-
voltage machine is running. Only use the grease recommended
by the manufacturer. If the grease drain holes are sealed with a
plug, (IP54 drive end; IP23 drive and non-drive end), remove plug
before commissioning. Seal bore holes with grease. Replace
prelubricated bearings (2Z bearing) after approx. 10,000 h -
20,000 h, at the latest however after 3 - 4 years.
